5. Call PS Configure Voltage Output with the following parameters:
• Channel =
ps/+6V
• Voltage Level = 0, as listed in the first row of the Verification Point column of
Table 20 or 21
• Current Limit = 1 or 3, as listed in the first row of the Current Limit column of
Table 20 or 21
6. Wait at least 150 milliseconds for the DC power supply to settle.
7. Measure the output voltage with the DMM and record the reading. Subtract the DMM
reading from the verification point. Verify that the calculation falls between the limits in
Table 20 or 21.
